Fixed inductors are commonly used components of electronic circuits. They are used for AC induction, DC blocking, and filtering applications. Fixed inductors can range in size from small surface-mount devices to large leaded components. The purpose of fixed inductors is to create an inductive loop in a circuit.

Inductors are typically made from a ferromagnetic material such as air core, ferrite core, or iron core. These materials will have different magnetic properties such as permeability and reluctance. The inductance of the inductor is determined by the size of the core, the number of turns, and the type of material used for the core.

The most common type of fixed inductor is the air core inductor. An air core inductor is a simple inductor made from a single ferromagnetic core wound with wire. The air core inductor has several inductors in series, which increases the total inductance. Air core inductors are commonly used in high-frequency applications. They are also the most cost-effective option for larger inductors.

Ferrite core inductors are more complex and typically more expensive than air core inductors. They are made from a combination of a ferrite material and a winding. Ferrite core inductors are widely used in power electronics, radio-frequency applications, and motor control applications.

Iron core inductors are the most expensive type of inductor. They are made from a ferromagnetic material, such as a steel core, and a winding. Iron core inductors are commonly used in applications where high inductance is required, such as power supplies, switch mode converters, and other electronic equipment.

The size and operating frequency of a fixed inductor determine its application field and working principle. In general, the larger the size and the higher the operating frequency, the more effective the inductor is at storing energy. As the operating frequency increases, the inductance value of the fixed inductor also increases.

At lower frequencies, inductors are mainly used as passive components to store and release energy, and reduce circuit noise. At higher frequencies, they are used as active components to increase circuit efficiency and reduce losses. Inductors can also be used as filters to reduce RF interference and improve signal quality.

Fixed inductors are rated in micro-henries (µH) or milli-henries (mH). The inductance rating of the inductor is typically specified in its part number, along with the inductor size and operating frequency. The operating frequency is usually given in the form of a frequency range, such as 10 to 300 kHz.

In summary, fixed inductors are used in a wide range of applications, from low-frequency AC induction to high-frequency DC blocking and filtering. The size and operating frequency of the inductor determine its application field and working principle. Inductors are usually rated in µH or mH and the operating frequency is usually specified in the form of a frequency range.
